Enabling it causes a couple of build failures though: drivers/pci/controller/pci-thunder-ecam.c:119:30: error: shift count >= width of type [-Werror,-Wshift-count-overflow] drivers/pci/controller/pci-thunder-pem.c:54:2: error: implicit declaration of function 'writeq' [-Werror,-Wimplicit-function-declaration] drivers/pci/controller/pci-thunder-pem.c:392:8: error: implicit declaration of function 'acpi_get_rc_resources' [-Werror,-Wimplicit-function-declaration] Fix them with the obvious one-line changes.
